Azure VNet Peering

In this Azure article, we will discuss VNet Peering, its types, benefits, limitations, Azure VNet peering cost, etc.

VNet Peering

  • Virtual network peering in Azure is an excellent concept that helps you to connect multiple virtual networks in Azure seamlessly.
  • VNet peering helps you to route the traffic between the virtual networks privately.
  • When multiple Virtual machines are present in peered Virtual networks, the benefit is that they can communicate with each other as they belong to the same network.

Types of Virtual network peering in Azure

There are two types of Azure Virtual network peering available.

  1. Virtual network peering
  2. Global VNet peering

Virtual network peering

Here, you can connect multiple Azure virtual networks in the same Azure regions.

Global VNet peering

In the case of Global virtual network peering, you can connect multiple Azure virtual networks across different Azure regions.

Benefits of VNet peering in Azure

There are some cool benefits that you will get with the use of Azure VNet peering.

  • Your Azure resources can communicate seamlessly even though they belong to different networks.
  • The Azure resources in different virtual networks will have high bandwidth and low latency rates.
  • While creating the peering, there is no need for any downtime to the Azure resources.
  • Another good thing is that the Azure virtual networks you will use for the virtual network peering can belong to either the same or different subscriptions.
  • There is no need for encryption or public internet, etc, for the communication between the networks.

Azure VNet peering limitations

  1. Transitive peering is not supported here. To make it clear, let’s consider a scenario: Suppose X has peered with Y, Y has peered with X but has not peered with Z.
  2. In case your virtual networks have matching CIDR blocks, then in this scenario, you cannot create the virtual networks peering.

Azure VNet peering pricing

Below is the pricing structure you need to consider if you want to use the Azure virtual network peering.

For the same region

In case the Azure virtual networks belong to the same region, then you need to pay $0.01/GB for inbound data transfer and $0.01/GB for outbound data transfer as well.
